This is going to be a bit of a unique competition, maybe.
Have you ever done those IQ tests where they give you 4 numbers in a row and you're supposed to see patterns and guess what the 5th would be? Think of this that way.
I will place a row of numbers and you will have to guess the next two.
20, 320, 1000, 900, 1800, 3900, 16000, ___ , ___ .
How the winner is chosen will be announced in 1 day. :)
